    ABSTRACT
    The discovery of an evolutionary lineage of New Caledonian Eumolpinae (Coleoptera Chrysomelidae) with intermediate characteristics between the New Caledonia endemic Thasycles Chapuis, 1874 and the New Zealand endemic Atrichatus Sharp, 1886, and monophyletic with both genera in an mtDNA phylogeny, is used as an argument to propose the synonymy of both genera, Thasycles Chapuis, 1874 = Atrichatus Sharp, 1886 syn. nov. Moreover, the morphological and genetic diversity within this new lineage allows distinguishing three new species of New Caledonian Eumolpinae in the genus Thasycles, which are described in this work: T. modestus n. sp., T. purpureus n. sp. and T. quadraticulus n. sp. The last two species, particularly T. quadraticulus, only found above 400 m in Aoupinié, have to be considered narrow endemics at present. A pragmatic key for the identification of these species and the diagnosis of all genera of South Pacific Eumolpinae with hairy dorsum is presented.
